Why Is Bear Lake Incredibly Clear: A Natural Wonder

Why is Bear Lake not as blue as it used to be? This change in the lake’s color, though temporary, may indicate a more significant underlying issue. According to the environmental group known as Bear Lake Watch, this phenomenon is likely due to the influx of water from the Bear River, which is diluting the concentration of calcium carbonate particles responsible for the distinctive blue hue of Bear Lake’s water. This alteration in the lake’s appearance serves as a reminder that failing to appreciate and protect our natural treasures could lead to their eventual degradation and loss. This information was reported on July 6, 2023.

What causes the distinctive green color of Bear Lake? The intriguing phenomenon is attributed to the presence of Blue-Green Algae, which is not actually algae but a type of bacteria known as cyanobacteria. These cyanobacteria can be found in various bodies of water globally, including lakes, ponds, and reservoirs. Typically, they exist in small quantities; however, under specific conditions, such as in warm, shallow, and undisturbed surface waters exposed to substantial sunlight, they can proliferate rapidly. This natural process can result in the vibrant green hue that Bear Lake is known for, and it’s worth noting that this phenomenon was observed on June 1, 2023.

Is Bear Lake man-made? Bear Lake is not a man-made body of water; rather, it was naturally formed due to seismic activity along the eastern Bear Lake fault line. This geological process led to the subsidence of the Bear Lake Valley, resulting in the creation of this picturesque natural freshwater lake.
